74ABT377CMSA

Flip Flops Overview

The 74ABT377CMSA is an octal D-type flip-flop manufactured by onsemi, housed in a 20-lead Shrink Small Outline Package (SSOP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 200 MHz. The device features non-inverting outputs with a maximum propagation delay of 6.8 ns at 5 V with 50 pF load. Output drive capabilities include 32 mA source and 64 mA sink currents. Static current consumption is 50 µA, and the input capacitance is 5 pF. It functions reliably across an ambient temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Fully edge-triggered operation ensures predictable state changes synchronized with the LOW-to-HIGH clock transition.
• High impedance during power-up and power-down cycles prevents glitch-free bus loading issues.
• Guaranteed latchup protection enhances reliability under standard operating conditions.

Flip Flops Applications

• Octal data storage and buffering in high-speed digital systems
• Clock distribution networks requiring edge-triggered synchronization
• Bus interface circuits utilizing high-drive capability for signal integrity

Flip Flops Procurement Notes

Verify the specific suffix CMSA corresponds to the 20-lead SSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or component material declarations. Ensure the procurement channel provides valid traceability for the onsemi manufacturing origin. Cross-reference the ordering code against current datasheets to confirm availability and pinout compatibility.

Flip Flops Selection Notes

Select this component for applications requiring octal latching with ABT logic speed characteristics. The 20-lead SSOP package suits space-constrained surface-mount designs. Evaluate the 6.8 ns propagation delay against system timing requirements. Consider the 4.5 V to 5.5 V supply range for compatibility with standard 5 V logic interfaces. Assess the 64 mA sink current for driving heavy capacitive loads effectively.

Flip Flops Part Context

This part belongs to the 74ABT series of high-speed CMOS logic devices. It shares functional similarities with other octal D-type flip-flops like the 74ABT374 but includes specific enable features. The SSOP packaging distinguishes it from SOIC or TSSOP variants within the same logical family. It serves as a standard solution for parallel data registration in industrial and commercial electronics.

Flip Flops Replacement Considerations

Direct substitutes include SN74ABT377ANSR and SN74ABT377ADW from Texas Instruments. Verify pinout and electrical specifications match before implementation. Alternative packages such as SC or TC suffixes may offer different form factors with identical functionality.
